Answer 2

This solution need a workaround in sololearn if you want to get the marks as array.
Here is a code which shows how to get a user-defined array in terms of size and values:

first input is the size you want and the next ones are the actual values.
you can enter them like this:
5
23 13 67 99 17

now your program would have an array which you can access to make your calculations
